This is an abridgement of Jaami’ Al-‘Uloom wa Al-Hikam by the great imam Ibn Rajab Al-Hanbali, may Allah have mercy on him. Jaami’ Al- ‘Uloom wa Al-Hikam is the greatest explanatory commentary of the “Forty Hadith” by Imam An-Nawawi and the most profound. For this reason, the scholars attached great importance to it and considered it a valuable reference for the detailed explanation of those noble hadith which define the fundamentals of Islam – by that I mean the hadith in the original collection: Al-Arb’een An-Nawiwiya (The Forty of Imam An-Nawawi).
